"Rollover
In trading, a rollover is the process of keeping a position open beyond its expiry.
Many trades have an expiry date attached to them, at which point the position will automatically close and any profits or losses will be realised. In some circumstances, however, the trade can be rolled over. This means that profits or losses will be realised and the trade gets a new expiry. Often, a rollover will come with an associated charge.

LSE Rule on Roll Overs
When conducting a roll over trade or a sale and buyback, member firms should consider the volume of business that these trades account for, relative to the daily market turnover in the security. Member firms should ensure that they have adequate procedures in place to monitor this activity and controls to prevent customers circumventing these by using different methods to deal, such as opening a position by telephone whilst at the same time closing another using one of the member firm's web based systems.
Where these trades are conducted in less liquid securities, the market may see inflated turnover in the security which is actually only a customer buying and selling the same position. Undertaking such sale and buyback trades, in addition to the regular rolling of trades, could give a false or misleading impression to the market and the Exchange may consider this to fall under general conduct rules 1400.
